OPW Engineered Systems, a division of OPW Fluid Transfer Group, announces the availability of its new 890 Series “High Load” counterbalance. This extension of OPW's counterbalance product line has been designed for loading arms that are required to handle extremely heavy loads. A growing trend in loading and unloading operations due to more stringent regulatory requirements, heavy loads are the result of the presence of additional valving, safety breakaways, actuators, couplers, and vapor-recovery attachments.
The 890 Series counterbalance is easy to calibrate because its spring-tension adjustments can be completed with one bolt and one socket wrench, making it a true “one-man, one-arm” operation. The 890 is also ideal for extreme operating conditions, thanks to its ability to achieve motion from 55 degrees above horizontal to 25 degrees below horizontal, with a torque rating of 19,000 inch-pounds. A halo bracket ensures this versatile operational ability, which allows the operator to dial in the appropriate range of motion needed for a specific application. This high-load spring technology also gives the 890 the ability to handle a 50% higher load capacity without any of the potentially dangerous drift that can compromise load stability.
The design of the 890 Series also makes it a money-saver since it does not require the pneumatic system that is typical for loading arms that have a longer reach or additional weight from attachments. The absence of a pneumatic system means there is no need for costly air lines or the need to maintain an air supply at the loading platform. To guarantee the viability of the 890 Series in high-load applications, OPW put the counterbalance through more than 100,000 load cycles with a fully loaded arm — approximating decades of hard duty — with zero degradation in performance.
